1 Claim. (01. 93-365) My invention relates to improvements in spinner heads. particularly adapted for use in paper bottle making machines, and the object of the invention is to provide simple means for I oi! excessive heat generated between the spinning head and rim of the bottle during the spinning operation which might burn or otherwise deleteriously affect the bottle rim and eliminate the stopping of the machine for the purpose of 1 allowing the head to cool, and it consists of providing the head with an annular series of radial blades set angularly so as to generate a longitudinal current of air in a direction away from the article being spun, as hereinafter more paru ticularly explained.

Fig. 1 is a longitudinal sectional view though a spinner and showing a bottle blank carrying mandrel in axial alignment therewith, the bottle blank being shown in dotted lines.

I Fig. 2 is a side elevation of a spinner head showing the flanges extending from the head and the bottle mandrel in axial alignment therewith.

In the drawing like characters of reference indicate corresponding parts in each figure.

I l is a bottle body carrying mandrel of usual construction and carrying the spinning member 2 coacting with the spinning head in the usual manner.

3 indicates the bearing in which the spinner Q shaft 4 revolves. l is the spinner head. 0 is an annular member surrounding the head and secured thereto by any suitable means. The member i is provided with an annular series of radial blades I set at an angle as shown in Fig. 2 and serving, when the head is rotated in the direction of arrow, to generate a current of air lon- I gitudinally away from the bottle blank l (indicated by dotted lines in Fig. 1) to carry the head caused by frictional contact between the head and the portion spun as it is given oil by the blades away from the bottle blank so that it will not detri- 1 mentally affect the same.

It has been found that after spinning a hundred bottles, the spinning tools become very hot and the machine has to be stopped in order to allow the spinning members to cool. By my in- 1 vention this loss of time is obviated.

Although I have shown my device as applied to the spinning of the bottle mouth, it may be equally well applied to the spinning in of the bottle bottom or to any other spinning operation. 10

what I- claim as my invention is:-

In a spinning device, in combination a bottle body carrying mandrel, a spinning member, a spinner shaft, a spinner head, an annular member suitably held on the spinner head and provided with a series of radial blades angularly set so as to throw a current of air backwardly away from the endedge of the bottle blank as it is being spun.
